Sample entries for [IMSIPref Rules] section:

1. 2163039 = B, 3,W

It means if the IMSI is in the given IMSI range (2163039*) and the IMEI is in the IMEIList3 then the status of the equipment will be set to "WhiteListed".
If the IMEI is not found in IMEIList3 the answer will be "BlackListed".

2. * = U, 1,B, 2,G, 0,W

This is the default setting, when the IMSI is not fit to any ranges defined in the INI or there is no IMSI at all in the checkIMEI message.

The status will be
• "BlackListed" if the IMEI is in IMEIList1
• "GreyListed" if the IMEI is in IMEIList2
• "WhiteListed" if the IMEI is found in IMEIList0
• "UnknownEquipment" otherwise.
